Title: Search apparatus
Inventor: HOLT NICHOLAS PETER
IPC: G06F17/30
Filed: 1986-04-23
Abstract: Search apparatus is described for locating an item which satisfies a predetermined criterion e.g. an instruction ready for execution or a free block of data. The apparatus uses a tree structure where each terminal node represents one of the items and is set if that item satisfies the criterion.
